Grand Facts

About Your Grand Valley Flask

A Jacob Bromwell® product is an investment for life. Copper is sky-high on the commodities market today, and there are up to five red-blooded American workers involved in the creation of this copper masterpiece. Every step in our unique manufacturing process is still done by hand. It's a passion our company is unwilling to give up. See how it's made here at our Factory Tour!

A Jacob Bromwell® original design. Bromwell is the original manufacturer of these quality copper flasks! Other companies may imitate the original Bromwell design. None are made as well, and none have the history to back them up.

Made of pure, solid copper and features our proprietary hot-tinned interior. Considered to be a long lost art, hot-tinning is a manufacturing process pioneered by Jacob Bromwell® nearly 200 years ago. As a highly-skilled, labor-intensive process, we take sheets of tin and apply it through a process of heating directly to the copper. Hot-tinning makes each piece unique and historically-correct to the original design, and ensures your product is food and beverage safe.

100% authentic and true to the original. Each piece is soldered with lead-free solder - not welded - for added authenticity.

It makes a great desk accessory item. In addition to its functionality, this prized possession also makes a great desk accessory item.

Copper will never rust. Copper is resistant to corrosion and will never rust. If left untreated, the copper finish will naturally oxidize and age beautifully. You can polish it up to restore its shiny finish, or let it earn a beautiful patina.

A little shaky with your liquor pours? We highly recommend adding our beautiful copper funnel so you can fill your flask without spilling a drop!

Product care: Hand wash only. Do not place in dishwasher.

Dimensions and weight: 1.5 x 5.5 x 4 (inches), 1.50 (pounds).

Minor cosmetic imperfections may occur. Small imperfections are a natural part of the handmade process and lend charm, depth, and individuality to each piece.

This product is guaranteed for life. Your purchase is backed by our 100% Lifetime Guarantee, so you can buy with confidence.

It's proudly made in America. Still Made in the USA, even after all these years. Buy American and save jobs.

"Do yourself a favor and grab this flask while you can. It's might just be the nicest flask ever made."

Product Reviews

Andrew

I wanted a unique flask to carry when I was going for a school reunion, just to show off a bit. Bromwell definitely served the purpose while keeping my liquor safe. It helped make some great reunion memories.

Luke

I was a little worried after I read about the manufacturing process in the little card that accompanied the product. Was the old handmade method going to withstand my using style I shouldn’t have worried at all as there’s no leakage because of the soldering used to make it.

John

Don’t be misled by this simple looking flask. It is hand made from copper ensuring that there will be no rusting. Additionally, the cork screw cap makes sure that the liquor doesn’t spill or leak.

Wyatt

What a great flask to carry any liquor around! It normally carries at least 8 shots of my favorite tequila, a perfect companion in case you are going on a long trek.

Henry

The dented copper casing was the first thing I noticed when I received this product. Later, when I read that it was handmade in the US Bromwell factory, this made it a standalone piece.

Henry

I have had this flask since a few years now and it has never disappointed me. I have purchased the copper funnel to help with the refill and opted for the stopper than the screw top. In spite of it, happy to report, there are no spillage at all.

Lucas

I read that this design in an original Bromwell one that has been around since last 200 years. This is said to be the biggest flask that Bromwell offers and I’m happy I got it.

Emily

This is a great gift in case you have a whiskey connoisseur in the family. I bought one for my uncle and now see him carrying it everywhere in his pants or coat pockets

William

I wanted something that would hold more than 3 pegs of my bourbon but wasn’t able to find one, other than the regular batch-made flasks. I wasn’t happy with the quality of my old flask which is when I was recommended to try Bromwell. The lifelong guarantee and the heavy to touch copper casing made me pick this up.

Michael

A great gift from my grandkids. I always carry it when I go out, especially during winter, and always see someone complimenting it.

Mason

This flask looks old fashioned but works perfectly. I learnt about how it is made from scratch by artisans and have been extra careful when I use it.

Oliver

I didn’t know I was making a lifetime purchase when I bought the Grand Valley flask. In spite of dropping the flask in water while out camping and dumping it in rucksack with heavy items, the flask has held its shape and liquor without any worries.

Liam

The copper flask with the screw top is something I have carried with me in my rucksack, suitcase and coat jacket without being worried about any liquor sloshing and spilling. A great product!

Jason

This copper flask reminds me of old movies, which is why I picked this up. I was impressed with the amount of liquor it holds without any leakage.

James

I am a fan of custom made items and this flask was no different. I purchased this product for myself as a gift because I wanted to get something that looked a little antiquated.

Noah

I got this as a gift and had left it in my office. I’ll have to admit that I occasionally used it as to hold stray papers until one of my colleagues asked to borrow it and had only good things to say about it.

Alexander

Though I had read about hot tinning process, I didn’t realize that this is still actively used to treat copper vessels until I read about the Bromwell flasks. With this product, I know that I’m carrying a flask that’s 100% safe to use lifelong.

Jacob

It’s surprising to see a handmade flask made from hammered copper sheets look so elegant. The shape of this flask makes it easy to carry around in jackets.

Benjamin Ross

I purchased the Grand Valley flask as a camping accessory and I haven’t regretted this decision at all. It looks rugged and elegant at the same time and can hold a good 8 shots of liquor.

stephen

5/5 stars. no complaints. love the stopper look instead of the screw top look.

Kirk

Very nice looking flask. The hand hammered finish is amazing...you can tell it's done by hand and not some machine. I would think that it would cost more.

Ruben

I like this one a lot - it has a chain and a permanently attached stopper. It's the best of both worlds - the hammered look with the stopper, instead of the screw top. I guess it's all a matter of preference, but I like the old school ones like this more...more character!
